A request change unit outputs a command as a request under control of a judgment control unit. A response condition determination unit determines a condition that is to be matched by a correct response which is to be returned from the other device-in-communication in reply to the command if the other device-in-communication operates in conformity with a protocol. A check unit checks a response received from the other device-in-communication in reply to the command, against the condition. If the received response does not match the condition but is correctable to match the condition as a result of the check, a response correction unit corrects the received response to match the condition under control of the judgment control unit.

A multi-processor control device according to an example of the invention comprises a cooperative control unit which determines priorities of requests issued from processors to a shared resource which are used to suppress a total power consumption of the processors within a range in which performance constraints of programs executed by the processors are satisfied, and determines a frequency of each of the processors so as to suppress the total power consumption within the range in which the performance constraint of the each program is satisfied, a first control unit which issues requests from the processors to the shared resource in accordance with priorities determined by the cooperative control unit, and a second control unit which controls the frequency of each of the processors in accordance with the frequency determined by the cooperative control unit.
